06 Prerunner Front Suspension Noise

Since I bought my truck, I have noticed fairly loud suspension noise from passenger's side front wheel when it is compressed at full lock. For example, if I make a uturn and don't quite make it all the way around without my front outside wheel going into the gutter it will happen every time. It is a low pitch squeak as if something is binding, and it only happens under these circumstances. I thought it may have been the shock, but I recently changed mine out for TRD billies and the noise did not change at all.

I had my suspension "looked at" when I was trying to get the TSB performed, but they never mentioned anything. It's not a huge deal, but I was wondering if anyone else had this problem. I don't have any reason to believe the truck was modified or seriously off roaded before I bought it.
